Abstract
The utility model discloses a maintenance and shaft changing operation platform for a crowned teeth connecting shaft of a vertical mill, which belongs to maintenance facilities. The platform adopts a structure that a hydraulic pump station is fixed on one surface of a support frame on a base; the other surface of the support frame is provided with a lifting bracket with a roller wheel; a shaft changing workbench is fixed on the lifting bracket; two flattened sockets which are matched with a bell mouth of the crowned teeth connecting shaft of the vertical mill are fixed on the shaft changing workbench; a lifting beam is arranged on the top of the support frame; a top beam of the lifting beam is supported by two hydraulic lifting oil cylinders; two fixed block type chain wheels are arranged below the top beam; a chain is suspended on the chain wheel; one end of the chain is fixed on the lifting bracket, while the other end is fixed on the support frame; when the hydraulic oil cylinder is lifted, the top beam drives the chain wheel to hoist, thus the shaft changing workbench is hoisted simultaneously. The work platform is used for replacing the transmission shaft of the vertical mill in the production of wire rods and rod materials.
Description
Technical field
The utility model relates to maintenance of equipment, changes the equipment of vertical mill power transmission shaft in especially high line, the production line of bar.
Background technology
At present the iron and steel production line of bar is overhauled when especially changing vertical mill barreled tooth flank connecting axle, owing to there is not inspection platform, the people stands on the mill housing and works, and the underfooting greasy dirt is many, the tumble injury of easily slipping; This operation belongs to work high above the ground, and overall process uses jack and suspension hook to rise and fall, because size is big, and 1 ton of multiple amount, poor stability, inefficiency, lifting is inconvenient, changes difficulty, causes maintainer's labour intensity to strengthen, and the working time is long, and operating efficiency reduces.
Summary of the invention
The purpose of this utility model is that the maintenance replacing that solves vertical mill barreled tooth flank connecting axle makes things convenient for problem, and a kind of job platform that changes is provided.
Structure of the present utility model is: it comprises base and the bracing frame that is fixed on the base, the one side of bracing frame is fixed with hydraulic power unit, the two columns inboard of bracing frame is a chute, install the shears of band roller at the another side of bracing frame by chute, be fixed with on the shears and change a workbench, the top of bracing frame is equipped with the lifting beam, the lifting beam is made up of the slide post of back timber and both sides, the back timber of lifting beam is supported by two hydraulic lifting oil cylinders, the sprocket wheel of two fixed pulley formulas is installed under the back timber, hang with chain on the sprocket wheel, one end of chain is fixed on the shears, and the other end of chain is fixed on the bracing frame, when hydraulic jack rises, back timber drives sprocket wheel and promotes, and changes also rise together of a workbench thereby make.
To change axle work conveniently in order making, to change and fix two homalocephalus sockets that are complementary with vertical mill barreled tooth flank connecting axle horn mouth on the workbench.When changing spool new connecting axle horn mouth inserted and stand on the homalocephalus socket, open hydraulic power unit hydraulic pressure is provided, change the height and position that a workbench slowly rises to needs to change old connecting axle, trade in an old for a new one.
Good effect of the present utility model is: provides Special Equipment for the upright trailer of high line bar changes axle work, changed a time weak point, and high efficiency, easy to operate, labour intensity is low, and work safety.

The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3.The utility model embodiment comprises base 1 and the bracing frame 6 that is fixed on the base 1, the one side of bracing frame 6 is fixed with hydraulic power unit, the two columns inboard of bracing frame 6 is a chute, install the carriage 4 of band roller 5 at the another side of bracing frame 6 by chute, be fixed with on the shears 4 and change a workbench 2, the top of bracing frame 6 is equipped with lifting beam 8, lifting beam 8 is made up of the slide post 12 of back timber and both sides, the back timber of lifting beam 8 is supported by two hydraulic jacks 10, the sprocket wheel 7 of two fixed pulley formulas is installed under the back timber, hang with chain 11 on the sprocket wheel 7, one end of chain 11 is fixed on the shears 4, and the other end of chain 11 is fixed on the bracing frame 6, when hydraulic jack 10 rises, lifting beam 8 drives sprocket wheel 7 and promotes, and changes also rise together of a workbench 2 thereby make.
To change axle work conveniently in order making, to change and fix two homalocephalus sockets 3 that are complementary with vertical mill barreled tooth flank connecting axle horn mouth on the workbench 2.When changing spool, new connecting axle horn mouth inserted stand on the homalocephalus socket 3, open hydraulic power unit 9 hydraulic pressure is provided, change the height and position that a workbench 2 slowly rises to needs to change old connecting axle, trade in an old for a new one.
